Our invention relates to improvements in mooring chocks, and the object ot' the invention is to devise a chock of this type which will lead the cable from any desired direction and automatically adjust itseli2 to any desired `change of lead, which will prevent the cable slipping out of engagement and thus eliminate liability to accident during replacement, which is so constructed that it may be secured in place without liability to produce leakage to the supporting structure, and it consists j essentially ot the arrangement and construction of parts as hereinafter more particularly explained. c

Fig. 1 is a sectional View through our chock showing it placed in position upon the supporting structure such as a ships deck.

Fig. 2 is a sectional view through Fig. 1 on line 2 2.

Fig. 3 is a sectional view through Fig. 1 on line 3-3. i

In the drawings like characters of reference indicate corresponding parts in each figure.

1 indicates the main supporting standard oi the chock which is secured to a deck 2 in proximity to the gunwale 3. 4 is a cylindrical body formed integral with the upper end of the standard 1 such standard tapering upwardly from its base as clearlyindicated in the drawing. 5 is a cylindrical member which is turnably held in the cylindrical body 4 which forms a journal bearing therefor.

The exterior of the member 5 is cylindrical to lit the internal cylindrical orifice of the body 4, its interior being substantially diamond-shaped as indicated at 6 in Fig. 2, the corners of the diamond being rounded off as indicated at 6X and 6. The outer e'nd of the cylindrical member 5 is flanged annularly as indicated at 7, the inner face of the liange bearing against the outer end of the body 4. The inner end of the member 5 protrudes from the oriiice of the body 4, such protruding portion being provided with an external thread 7 8 is a securing nut which is screwed on to the threaded portion 7X and is permanently secured in place by means of a grub screw 9.

10 and l1 are lugs extending from the outer face of the flange portion 7 depending downwardly and outwardly ininclined direction. 12 is a shaft secured'in the lugs 10 and 11 upon which is mounted a flanged pulley 13.

14 and 15 are upward extensions of the lugs 10 and 11 between which is secured a counter- Aweight 16, such counterweight serving to counter-balance the weight oi the pulley 13 so that it will be held in any place to which it is swung around its centre of motion between the lugs 10 andll. Above the pulley 13 is secured a block 16 by means of a bolt 17 and a Cotter pin or similar withdrawable'device 13. 19 isa cable passing through the cylindrical member beneath the lower end of a block 16 and over the pulley 13 outwardly over the shipsside, y

i lnV order to enable the cable 19 and any securing device such as a snap hook secured to the end of the cable, being passed over the pulley 13, we withdraw the Cotter pin 18`so that the block`16`may be swung up to permit the passage of the hook, the block 16 may be then replaced its lower edge serving to guide the cable and prevent it slipping out from between the ilanges yof thev pulley. Very often a cable slips from its place'on the pulley `so that there will always be a direct draw from the cable on to the pulley, the counterweight 15 serving to hold the pulley definitely y into any place to which it is adjusted.

From this description it will be seen that we have devised a very simple construction4 of mooring chock, which will automatically adjust itself to any desired position during operation and from which there will be no danger of the cable being displaced and thus producing liability to accident during replacement. j

That we claim as our invention is 1. A mooring chock comprising a main standard member adapted to be secured to Y a ships deck in proximity to the gunwale and i having a hollow cylindrical orifice at its .up-

ably fitting thevorifice and secured from longitudinal movement, lugs extending from the cylindrical member in an outwardly in- ,olined direction, a shaft journalled between the members of the lug, a grooved pulley mounted upon the sliait,1neans for maintaining the cable passing through the cylindrical member over the pulley in engagement with the pulley groove, extensions extendingv upwardly from the lugs, and a counterweight secured between such extensions.
